Hi,

You need to change the resolution within grub, which is advised if you have a 4k screen for example. (grub is also very slow on 4k screens)

in /etc/default/grub file, and add/replace the following line=

GRUB_GFXMODE=1280x1024x32,auto

Then run “update-grub” to update the GRUB.
This will run GRUB in 1280x1024x32 resolution, which is the workaround for this problem.
Please make sure the resolutiion is supported. The “auto” means that GRUB will fallback to auto detect in case the resolution isn’t supported.

Thank you. Changing that line does solve the problem. Just realized I'm barking up the wrong tree though, I'm after automating this on system installation.
